I agree, no discipline whatsoever.
I actually spoke to a young woman in the coffee shop yesterday - the children with her were about 5 and 3, and were running wildly up and down the middle of the shop, making a heck of a racket and attracting a lot of tutting, but she was completely ignoring them, just talking to the other young woman with her. At one point the smallest almost ran into a waitress who had a tray of hot drinks, she had to turn sideways and raise the tray to shoulder level, and I'd had enough
"Excuse me! The little girl almost tripped the waitress up there, her running wild in here like this is dangerous"
She looked at me blankly and for a moment I thought I was going to get a mouthful of abuse, but she just said "Oh thanks.." and asked the children to sit down............
